To all whom t may con-cern.'

Be it lrnown that l, MORRIS GARDNER TAL- Co'r'r, a citizen of the United States, residing in Talcott'ville, in the county of Tolland and State of Connecticut, have invented a new and improved @il Burner, of which the following is a specification.

My invention relates more especially to the class of oil burners employing fluid, as air, Linder pressure, as an agent for yatomizing or mixing, and an object ofmy invention, among others, is to increase'the efficiency of such oil burners. 1

One form of burner embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view in lengthwise section through the outer end of an oil burner, including the burner tip, embodying my invention.

Figure 2 is an end view of the same.

Figure 3 is a detail view, scale enlarged, in cross section through the burner tip looking toward the end.

My invention relates to the well known class of oil burners consisting of a nozzle including an outer tube for supplying air and an inner tube for supplying fuel, as oil, the air and oil being mixed to a greater or less extent before they emerge at the end of the nozzle. Als the general structure of these nozzles or burners is well understood by those skilled in the art only the outer end thereof has been shown by me in the drawings herein for the purpose of illustrating my invention.

ln the accompanying drawings the numeral 5 indicates the outer tube of burner that may be of any desired shape, prefer-` ably round, and that will be connected at its inner` end with any means for supplying fluid, as air, to the mixing chamber 6 within the burner. A fuel supply pipe 7 extends from any suitable supply of fuel, as oil, within the chamber 6 to or near the outer end thereof, it'being understood that the fuel will be supplied underv such pressure as may be desired, the tubes being 'of such relative size and the pressures being regulated to supply the proper amounts of fuel and air for the special purposes for which the burner may be employed, my improved burner being especially adapted for use with air under low pressure and with anoil pressure as may bedesired. i

A novell feature of'fmy .improved devicey consists in thev means' for spreading the oil and` causing it to be thoroughly mixed with the `air, such device embodying aspreader havmgareceiving-recess located in the path of movement of thezoil as it is forced out of the pipe 7, this recess thus causing-the ,oily tobe thrown baclrwardly andfoutwardly in a spray.. This spreader and receivingrecess may be arranged ,invarious ways to accomplish the desired results, in the. `structure herein shown altip 8 yhaving.. an voil pa'ssage9 extending therethrough being secured to the end of the pipe The inner end 1() of the tip is recessed to forman annular chamber between it and the inner surface of the pipe, and in the structure herein shown a ange l1 on the tip rests against the end of the pipe, the tip being preferablysecured to the pipe as by means of intermeshing screw threads.

A cap 12 isscrewed onto a nipple 13 projecting from the tip, said cap 'comprising a` spreader 14 supported by posts 15 extending from its base and disposed to provide outletA openings 16. l y 'A receiving recess v17 is formed on the inner surface of the spreader and opposite the mouth of the passage 9, this recess being preferably of conical shape and located directly opposite the passage 9, so that as the oil or other fuel under pressure is forcibly ejected from said passage, such fuel will enter the receiving recess, thesloping walls of which will cause the fuel to be thrown backwardly in a diagonal direction through the outlet openings 16 into the current'of outcoming air. This causes the fuel to be divided into a very fine spray and to be thoroughly comminged with the air, thus producing a mixture in prime condition for ignition at the mouth of the burner, which burner will be proj ected into the combustion chamber, as of a furnace or other structure.

The posts 15 are preferably tapered from their inner edges outwardly, thus offering little obstruction to the passage of fuel as itv passes out from the receiving recess in the spreader.

In accordance with the/provisions of the patent statutes, I have described the principles of operation of my invention, together with the device which l now consider to represent the best embodiment thereof; but I desire te have it understood that the device shown is onlj,7 illustiative7 and that the in- Ventiou may be carried out by other means.

claim- 1. A. burner comprising a fuel supply pipe, an air tube surrounding said supply pipe and having an unobstructed open mouth concerk tric with said supply pipe, and a spreader having an unobstructed receiving recess its under surface to receive the oil separately 'from the air, and `force such oil, as it passes from said pipe, barzliwarclly into the air currents in the open mouth oi said air tube.

` 2, burner couunrising- Yfuel supplypipe, an tube suirounding` said supply pipe and having; au unobstructed open mouth concentric with said supply pipe anda cap secured to said pipe and havingI spreader located lopposite the mouth of saidpipe with a clear and unobstructed space between the entire end of said pipe and said spreader and mouth, said lspreader Comprising an imperorate surface with a receiving` recess in its inner 'face Vlocated opposite the outlet from said pipe to receive uel separately from the air a. such fuel is delivered therefrom and te throw it baelrwardly in a spray into the air currents in the open mouth of said air tube.

8. A burner comprisinga tip including` a bod57 having a fuel passage therethrough1 and a Cap secured to said body and comprising spreader located opposite the mouth of said 'fuel passage and having' an imperforate surl'face including a. recess in said surfaee epposite said fuel passage to deliver 'fuel in substantially all direetions backward aud laterally outwardly 'from the sides ot said cap.

ai. A burner comprising au air tube, a Fuel supply pipe located Within said tube, and a cap secured to said pipe aud comprising posts ith a spreader secured to the outer ends of the posts and an unobstructed receiving recess located in the under surface of said cap opposite the opening from said supply pipe.
